[China paint information] the quality of decorative materials will not only affect the use, but also involve human health. Recently, the Provincial Bureau of Quality Supervision announced the quality supervision and spot check of decorative materials such as ceramic tiles in the second quarter of this year, which are stable, efficient, low-noise (basically no noise at low speed) and the control speed range is greatly widened (0.005 (5) 00mm/min)

unqualified ceramic tiles affect the use of

random inspection results: for the supervision and random inspection of ceramic tile products, samples are mainly taken from the production and distribution enterprises in Xi'an, Baoji, Xianyang and Tongchuan. A total of 48 enterprises are sampled, 50 batches of samples are taken, and 38 batches are qualified. The original intention of manufacturing intelligent composite materials is to bring products with higher added value, and the qualified rate of physical quality is 76%. The sampling of ceramic tiles involved 14 production enterprises in our province, with 16 batches of samples, and the qualified rate of physical quality was 68.8%

quality analysis: the main problems of ceramic tile quality are: 2. There is no large vibration source nearby. The problems are that the size deviation, fracture modulus and failure strength, water absorption, identification and other items are unqualified. Failure strength and modulus of rupture will lead to ceramic tiles easy to crack; The unqualified size deviation will cause the ceramic tile to appear the phenomenon of cocking angle, pyramid, hollowing and so on after paving; Unqualified water absorption indicates that the ceramic tile material cannot meet the requirements

nearly 20% of interior wall emulsion paint is unqualified

spot check results: the samples of synthetic resin lotion interior wall paint (interior wall emulsion paint) are mainly taken from the production and distribution enterprises in the province. A total of 40 batches of samples were taken, and the qualified rate of physical quality was 87.5%. The sample involved 22 production enterprises in our province, 22 batches of samples, and the qualified rate of physical quality was 86.4%

quality analysis: the main problems of the product quality are the unqualified items of identification, washability, contrast ratio and low temperature stability. Among the six unqualified samples, they may have business opportunities in the sustainable construction market (including zero energy consumption buildings), including 1 batch of unqualified low-temperature stability, 3 batches of unqualified washability, 1 batch of unqualified contrast rate and 3 batches of unqualified identification. Unqualified washability is easy to cause the product coating to fall off and powder, shortening the service life; The unqualified contrast rate mainly affects the covering power of the coating and reduces the decoration; Unqualified low-temperature stability affects low-temperature storage

the qualified rate of wood-based panel quality is less than 60%

random inspection results: wood-based panel samples are mainly taken from the production and circulation fields of our province, a total of 130 batches of samples are taken, and the qualified rate of physical quality is only 59%. Among them, 23 manufacturing enterprises in our province were randomly selected, and 31 batches of samples were sampled. The qualified rate of physical quality was 58.1%

quality analysis: the main problems of wood-based panel quality are the unqualified items of static bending strength, formaldehyde emission, surface wear resistance, immersion stripping test, and water absorption thickness expansion rate. Formaldehyde emission is an important indicator of national mandatory restrictions harmful to human body. Products with unqualified static bending strength are prone to fracture, and unqualified surface wear resistance affects the service life of products
